Unit 13 3.1 – Solve practical and technical problems

Video

Some problems I might encounter whilst videoing my piece could be that the video might not be White Balanced. This is when you have to place a sheet of something white like paper in front of the camera and change the settings to ensure the piece gets colours correctly called RGB (Red, green and blue) which is when the camera is at 100%. If you don’t white balance the camera, then then it won’t be RBG so it could be over exposed. You are making the camera know what white is. There are two types of filming: interlaced and progressive. 1080p video is called progressive scan. 1920 x 1080 pixels in HD movies are progressively drawn line after line so they aren’t interlaced. Usually, films are filmed in 24fps (frames per second), TV is usually filmed in 30fps and PAL is 25fps.

Audio

The audio cable (left and right) is called an XLR and this could easily stop working in the film so this could be a problem I might encounter. We use Bars and Tone for calibration back when analogue recorders were used to setup the VTR (video tape recorder) to the same levels as were recorded by the original camera so that they got the best footage. It is also used at the start of the tape to lay down the start of timecode. Timecode is when you set the time of the film to hours, minutes, seconds and frames. This is how you identify a precise location of the film and is very handy when you are filming on more than one camera that may be filming at different times. A variation is known as time of day timecode, which means it records the actual time the recording was made rather than the time of the footage.

This is an example of Bars and Tone.
